CORK-PULLER.

SPECIFICATION forming part of Letters Patent N0. 728,518, dated May 19, 1903. Application filed August 16,1902. Serial lie-119.847. (No model.)

if ul improvements in cork-pullers and its object is to provide a device of this class which shall be simple, cheap, and effective in. operation.

The class of pullers to which my improved puller belongs is the typewherein a corkscrewcarrier and a threaded nutreciprocate in a snitable'guideway, the nut and carrier moving together half-way up said guideway, the carrier leaving the nut and moving up along the remainder of the g-uideway tostrip the cork, the carrier and nut then moving down, keeping the same distance apart until the nut reaches the bottom of the guideway, and the carrier then running down to the nut and screwing into the cork. This is one of several well-known types of pullers and, as heretofore explained, my improvements are in pullers of this type.

My invention consists more particularly in the devices which are used to cause the corkscrew carrier and the nut to preserve the proper relative positionsthat is to say, the

devices which look them together during thefirst half of their upward movement permit them to separate during the second half of the upward movement, keep them at a constant distance apart during the first halfof the downward movement of the carrier, and permit them to come together during the last half of the downward movement of the carrier. Hitherto the practice has been to use a system of positive locks between the corkscrew-carrier and the threaded nut, two hooks or some similar devicebeing usually used. In my puller I dispense with both of these hooks, replacing the positive lock between the carrier and the nut by adifferent device,

.opening. .nut isfree to move under proper impulse up and down-through the guideway, its mocork-pullers, and alloted Serial No. 119,849.

The broad idea contained in both these applii cationsis the controlling of the relative movement of the corkscrew-carrier and'nnt by preventing the rotation of the corkscrew rather than-by positively'moving them, ashas been done heretofore.

My invention is fully illustrated in the drawings accompanying this specification I andfuliy described in this specification.

In the aforesaid drawings, -Figure 1 is an elevation of the parts of my improved puller, one of the side plates of the case being removed. Fig. 2 is a similar view showing the nut and corkscrew-carrier in central longitudinal section. Fig. 3 is a section in the line 3 3 of Fig. 2. Fig. 4is a vertical section in line 4 4 of Fig. 2. Fig. 5 is an enlarged vertical longitudinal section through the corkscrew-carrier, theline of section being indicated by 5 5 in Fig. 6. Fig. 6 isa horizontal section in the line 6 6 of Fig. l, andFig. 7 is a front view of the cork-extractor with the handle partly broken away.

In the drawings, A is the case of the corkpnller, made in the usual form from two pieces out the greater portion of the length of the case. In this guidewayruns a nut B, threaded in the usualway to permit the corkscrew to run through it and provided with a lug b, extendinginto the opening a, and adapted to engage the stop a at the upper end of this It is obvious, of course, that the tion downward being limited by the guideway a and movement in the opposite direction being limited by engagement of the lug x corkscrew D of the ordinary type,which runs, as heretofore mentioned, through a suitablythreaded portion in the nut B. The corkscrew D is of course rotatable in the corkscrew-carrier C in the usual way. A lever E 10:

is pivoted in the case, and this lever is connected, by a suitable link e, to the corkscrewcarrier 0. It is obvious, of course, that the movement of the handle E will-reciprocate the carrier 0. The means by which the relative movements of the carrier and the nut are controlled consists, as heretofore pointed out, in preventing rotation of the corkscrew itself in its seat in the carrier during certain portions of the movement of the carrier. The means by which the power to rotate on the part of the corkscrew is controlled is by two ratchets G G upon the top of the corkscrew. The teeth on each of these ratchets extend in opposite directions, so that by engagement with a suitable pawl each can prevent the r0- tation of-the corkscrew in one direction. The ratchet G prevents rotation to the right and the ratchet G prevents rotation to the left when engaged by the proper pawl. Upon the carrier are pivoted two pawls H H, adapted to engage the ratchets G G, respectively. These pawls are pressed by springs h 7L toward the ratchets G G.

It is obvious that with the ordinary righthanded screw the corkscrew must be permitted to turn to the right when entering the corkthat is, when in the position shown in Fig. 2and must be permitted to turn to the left when stripping-that is, when the corkscrew-carrier is being separated from the nut in the upper portion of the movement of said carrier. Similarly, when it is desired to have the nut and carrier move together-that is, when pulling the cork-the corkscrew must be prevented from left-handed rotation-that is, it must be prevented from unscrewing and pulling out through the nut. Likewise when it is desired to have the nut and carrier move downward from the position shown in Fig. lit is necessary that the corkscrew be prevented from right-hand rotation-that is, that it be prevented from screwing into and through the nut. To accomplish these results, the pawl H must be engaged with the ratchet G. when moving down from the position shown in Fig. 7, thereby preventing right-hand rotation. It is immaterial whether or not lefthand rotation is possible. \Vhen the nut reaches the bottom of its course, the pawl H must be released from its engagement with the ratchet G in order that the corkscrew may enter the cork. It is immaterial, of course, Whether or not the corkscrew is free to rotate to the left during this portion of its motion, for the reason that there is no tendency for it to so rotate. When the pulling motion begins, however, the pawl I-I must be in engagement with the ratchet G in order to prevent left-handed rotation. It is of course wholly immaterial whether or not the corkscrew can rotate to the right when pulling, as there is no tendeney for it to so rotate. When the stripping motion is begun and the nut is arrested, the pawl H must be released in order to permit left-hand rota- It is, however, immaterial whether tion.

' there is any right-hand rotation. This brings us back to the beginning of the cycle. The motion of the pawls is controlled by two ribs I I, cast in and extending from the opposite halves of the case A. The rib I is in the bottom of the case, and its position is such that in the lower half of the motion of the corkscrew-carrier the pawl H is held out of engagement with the ratchet G. This leaves the corkscrew free to rotate to the right. The rib I does not reach the bottom of the case,and the spring h therefore holds the pawl H in engagement with the ratchet G and prevents left-hand rotation of the corkscrew when the corkscrew-carrier is in the lower half of the case. This, it will be seen, gives exactly the motion which it ought to have-- that is, it'will enter the cork, turning to the right, but cannot unscrew by turning to the left when pulled backward. In the upper half of the case the state of affairs is reversed. We lind the rib I holding the pawl H away from the ratchet G, permitting lefthand rotation, while the spring it holds the pawl H in contact with the ratchet G, preventing right-hand rotation. This, it will be seen, permits the cork to be stripped, but prevents the carrier from approaching the keep the same distance apart.

The simplicity and effectiveness of this de vice will be readily apparent to any one having any knowledge of the complicated systems heretofore in use for-securing the proper motion of 'the corkscrew and carrier. This form is extremely simple and cheap and exceedingly effective.

I realize that considerable changes can be made in the details of construction, and I do not, therefore, desire to limit my invention to the exact construct-ion shown.
